This research investigates the acceptance of AI-generated video content on social media platforms among Egyptian Millennials and Generation Z users. A model, extending the AI Device Use Acceptance Model (AIDUA), was proposed, incorporating additional variables into the existing three-stage model. The study examined the impact of nine determinants on the final stage, whether users were willing or opposed to using AI technology for video content creation. These determinants encompassed social influence, hedonic motivation, anthropomorphism, technophilia, computer self-efficacy, performance expectancy, perceived effort, emotion, and information verification. The purposive sample comprised 461 subjects, and data were collected through an electronic questionnaire. Structural equation modeling (SEM) and path analysis were employed to test hypotheses and analyze relationships between variables. Results confirmed the study's hypotheses, demonstrating significant effects of the assumed determinants on users' inclination or objection to AI applications in video content generation. Notably, the study found no statistically significant differences in the study variables based on respondents' age groups.
